Ewwww. Thread like worm in my tank 5 Gallon Tank

So there i was, getting ready to turn off the light in my 5 gal invert tank, when I noticed some thread like things on the side of the glass. At first I thought it was on the outside and grabbed a rag and some cleaner. When it didnt come off, i decided to take a closer look. Low and behold, there are little thread like worm things in there. So, heres the question. What are they and how do I get rid of them? Are they something to worry about? Thanks in advance!

whats that? how do i get rid of it? it is something that can hurt my inverts and fish?

oh thank god! Im pretty sure thats what it is. I had an emergency happen with my 20h and had to put everybody in the 5 gal for 4 days. Im sure that and a mixture of some other factors, (possible overfeeding, (the fish were getting so aggressive and food seemed to calm everything down,) sudden HUGE bioload, some dead shrimpies on the bottom and I recently have had a plant die in there,) are what contributed to this problem. Since I dont have fish in there, how do I get rid of them without harming my RCS or MTS?

Planaria are caused by debris and uneaten food in the gravel. If not cleaned up it will eventually cause an ammonia spike, which could kill the RCS. Maybe use something tiny like airline tubing into a bucket you could check closely for shrimp before dumping?

they are moving, not fast, but def a little bit of a wiggle. Not like and inch worm, i can see some of them floating in the water and getting pushed by the current. You know how you'll get a little peice of lint in you glass of water? Thats what they look like.

Heres a link to a picture thats looks like what I have, but its in spanish, so i have no idea what it says.

Everyone in the link think that, yes that is planaria, and that they are not dangerous, just a nuisance. They also recommend heating the water to 35C for several hours...

Edit: 35C is 95F! I wouldn't try this unless there was nothing else in the tank and you have a backup 'cycle' (aka filter media or whatnot) on hand. I was just translating and didn't think about the actual logic of their claims...

thanks for the translation! I have some TSS in the fridge.... i think I will just van the gravel and add a fish to take care of what can be seen. I have another problem tho, I will post it in another thread, maybe you all can help me with this one too.
